XF 1.4Disadvantage of my website ending with "index.php" !!

Member

I am running this website www.forumhuru.com ,and recently I came across an information stating that websites ending with "index.php" i.e www.forumhuru.com/index.php is really bad for SEO and Google assumes domain.com/ and domain.com/index.php are 2 different pages.

Due to the reason above,I am thinking of changing it by discarding the index.php part of the website name.
